It seems that dedicated audio converters or transcoders like the KORG AudioGate support DSF audio format (Delusion/XTracker) and can convert it to classic WAV or other audio formats. WAVs can typically be further converted to one of the compressed formats to reduce the file size.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
